I could be wrong but I believe there hasn't been a single top name PreTrib 'celebrity' proponent who has ever dared offer an Olivet Discourse commentary, in which they go slowly verse-by-verse through the text. Not John MacArthur, David Jeremiah, Tim LaHaye, Jack Van Impe, John Walvoord, C.I. Scofield, Dave Hunt, Grant Jeffrey, nor even Chuck Swindoll - former president of Dallas Theological Seminary, academic world headquarters for PreTrib doctrine.
Get the top most famous PreTrib pastors, authors, lecturers, "intellectuals" in a room and ask them to take you verse-by-verse through the Olivet Discourse...and you're going to hear crickets.
You may find some 2nd and 3rd string guys who might be linked over at the (hilarious) "Rapture Ready" website...guys like Thomas Ice (who used to be LaHaye's 'waterboy') and some others.
